How you should handle missing data depends on the reason it is 
missing.  For example, it makes little sense to fill in # of pregnancies 
for males.  So, I'd be careful about using just any old command that 
handles missing data.

Within stata, giving the command "search missing data" yields a lot of 
suggestions.  The impute and ipolate commands may be 
useful.  http://www.stata.com/support/faqs/data/missing.html explains some 
ways to replace MD.  Lots of other stuff there too.
